Detached Eddy Simulation of the Flow over Bolund

Abstract:

Detached eddy simulation (DES) with wall function was used in the flow simulation over complex terrain. Bolund Island with an almost vertical upstream escarpment was simulated, which has abundant measurements. Different density grids with the same size domain were employed. Flow structure details and good results can be obtained when the grid size is a twentieth or smaller than the height of the island in large separation region, when using central scheme. DES has better performance than RANS in large separation region.
